"Since the Supreme Court decision, Republicans have been calling the Affordable Care Act "the largest tax increase in the history of the world." Politifact rates this false. Kevin Drum's got a table of the 15 significant tax increases since 1950, and the Affordable Care Act, which amounts to a tax increase of 0.49 percent of GDP, comes in 10th. Austin Frakt took Drum's table and made a chart...So no, the Affordable Care Act isn't the "biggest tax hike in history." It's not even the biggest tax hike in the past 60 years. Or 50 years. Or 30 years. Or 20 years...".* The Young Turks host Cenk Uygur breaks it down.
